There is a legend that one day she sent some of her subjects to a distant country, promising that no misfortune would befall them on the journey; when they were on the ocean, a large sea-monster threatened to capsize their ship, but disappeared upon the invocation of Saint Gertrude. In memory of this occurence travellers during the Middle ages drank the so-called “Sinte Geerts Minne” or “Gertrudenminte” before setting out on their journey.
